The P2DVD Interface uses experience gained from both the SR and MR series remote control
system. Designed to be used with existing consoles and DAW's and synchronisers the interface will
connect any Sony P2 Protocol serial port to the Pioneer RS232 Port.
The P2DVD Interface may be used The Pioneer V7300D DVD is a well proven industrial DVD player
with two unique features, 1) Lock to external video syncs, 2) RS232 Control. The combination of the
P2DVD interface and the Pioneer DVD player can replace U-Matic's and Beta's as a controllable
picture source. The advent of consumer DVD recorders to make copies in the transfer bay makes
DVD as simple to use as Beta or U-matic. The DVD provides the advantages of Hard disk, low
maintenance cost, and instant access with the picture quality and portability of tape.
Size 170x114x31mm
As a RS422 controlled Master with most RS422 synchronisers, Digital Audio Work-stations and
Console automation systems..
Note. For the P2dvd to communicate the Pioneer DVD-V7300D/V7400D.V8000 must be set to 9600
Baud, see advanced setup below.

Special Functions
Select Title
DVD's can have one or more titles, in order to select one of the titles (This could be reels or
episodes) locates to 00:00:00:01..00:00:00:09 are used as select title commands. A Locate to
00:00;00:00 will display the title list. It is not possible to directly locate a timecode number between
00:00:00:00 and 00:00:00:09, if you need to locate to a timecode position used as a select title
command then locate to 00:00:00:10 and use the jog wheel to find the frame.
Note: On SR and MR systems the Locate with pre-roll must be turned off or shift locate should be
used when trying to locate a title!
Position
Using the P2DVD all DVD's have a frame-count starting from 00:00:00:10, When you select a new
title it will start at 00:00:00:10. Once timecode is read the update the position after 10 frames.
If there is no timecode on the disk then a SET GENERATOR (Macro 85 on SR/MR Systems)
command may be used to set the timecode at any point.
Limitations
1) When emulating a RS422 machine the DVD must be the Master, it cannot vari-speed to lock so as
to slave to Timecode or Biphase. It has a faster response than tape but a slower response time than
a hard disk, locates to anywhere on the DVD take about 1 second. Once located it will respond to a
play command within one frame.
2) The audio output is only available in play forward.
3) Limited range of Jog and Shuttle speeds (1/25, 1/8, 1/4, 1/2, 1* and 10*).
4) Approximately 1/2 second delay when changing direction.
Notes:
Jog
The latest version of P2DVD firmware has improved jog performance, a special jog algorithm with
hysteresis is used to remove code jitter and improve the performance of DAW's whist jogging the
picture. The timecode output of the P2DVD can run a 1/25..1* play speed, at 10* play speed 6 frame
bursts of stationary code are output. The limitations of the DVD player in jog are 1) there is no audio
during jog and 2) during the transition from -1/2 and -1* the DVD will stop playback in order to load
the data buffer. Because of the hysteresis the transition points are different when increasing or
decreasing the speed. When using switched jog commands the following commands (without
checksum) will always set the appropriate speed.
Speed Forward Reverse
Step $21 $11 $10 $21 $21 $10
1/8 $21 $11 $18 $21 $21 $18
1/4 $21 $11 $2C $21 $21 $2C
1/2 $21 $11 $36 $21 $21 $36
1* $21 $11 $40 $21 $21 $40
10* $21 $13 $60 $21 $23 $60
When Jogging forward the DVD will stop on the second field, when jogging reverse the DVD will stop
on the first field. If the burnt in timecode (BITC) is recorded one field late it will appear as if the DVD
misses a frame on the direction change. For example four frames A1 A2, B1 b2, C1 C2, D1 D2 on
direction change the DVD will display B1 -> C2 or C2 -> B1, if the BITC is one field late the A2+B1 =
0, B2+C1= 1, C2+D1= 3 thus the BITC for B1= 0 and for C2 = 2 missing frame 1 on direction
change.

DIP SWITCH SETTINGS
The DIP switch is read regularly by the interface and may be changed at any time.
DIP Switch 1 RS-422 Device ID
The RS-422 Device ID tells the controlling device which machine it is controlling. The RS-422
interface can emulate the following devices:-
Switch 1 Emulation Device ID
Off Sony BVU-950 1S 1C
On P2DVD 1s A3
The Timecode standard is included in the Device ID and is set by reading timecode via the LTC
input.
DIP Switch 2 & 3
Pre 2004 Software only: Jog/Shuttle Mode
Jogging with timecode emulation is only possible at a constant speed, switches 2 & 3 allow the user
to select this speed. Below the selected speed the P2DVD will jog normally, when the selected Jog
mode speed is reached the P2DVD locks at the selected speed, to exit the Jog Mode the Jog
command must drop below 1/8th speed for 3 frames or go above 4* play speed.
A number of controllers only use either Jog or Shuttle commands and do not separate them, The jog
mode parameter is used for both Jog and Shuttle. For shuttle to operate normally Jog Mode should
be turned off.

Timecode Connections
LTC O/P
Current DVD frame-count + timecode offset converted to LTC timecode. Stationary timecode is
output for approx 1/2 second when stopped.
NOTE: The LTC output is only active when video syncs are present.
LTC I/P
Connect to the left channel of the DVD, timecode or timecode burst will be used in set the offset
between timecode output and the DVD frame-count. A phono cable with stacking connecter is
supplied with the unit. When the timecode on the DVD is received it is used to set the offset between
the timecode and the frame-count. A four second timecode burst at the start may be used to preset
the timecode output, allowing two channels of audio to be used.
Cleaning
Keeping the DVD Clean is VERY important, a dirty DVD will not replay Video, Audio or Timecode
Correctly. Use DVD or CD cleaning and polishing kits available from HiFi shops if necessary.
Timecode Phase
The time-code output of the P2DVD is generated phase locked to video sync's, the phase of the
timecode recorded on the DVD may not be the same.The difference between the recorded phase and
the recorded timecode will always be less than one frame.
Instant Replay Mod
The Pioneer 7300 provides only reverse play and 10* reverse, in order to provide more control we
have implemented an 'Instant Replay' key input that will locate 3 seconds back each time it is
depressed. In order to implement this it is necessary to modify the PCB as follows.
1) Link RN2 pin 5 to U2 (2681) pin 38
2) Link U2 pin 38 to J4 (RS422) pin 5
Connect an external push button switch connected across pins 4 & 5 of the RS422 line to implement.
note1: The DVD takes 1 second to make the locate!
note2: The instant replay time can be changed at location $7EED in the EPROM ($4B = 3 Secs)

CB Electronics MC-1
As it is not possible to slave the DVD we have introduced new software to allow the MC-1 to slave
to the RS422 port. To operate correctly you will need new software in the MC-1 if your unit was
supplied before April 2002.
Using the P2DVD as a Master
1) Ensure that Serial B Config is set to SYNC ENAb not SYNC ALL
2) If not using film set Unit Config to Tapeless
3) Set the unit config to SLV SErb
4) Connect the P2DVD to port B
5) Set the timecode on the MC-1 to be the correct value for the Start mark
6) Enable Chase on the MC-1 front panel.

Making DVD's
1) Use DVD-R
2) We use domestic recorders, very easy to use! set the compression ration, then request Record to
start and Stop to end.
3) If you want the original timecode, put a 4 second burst of timecode at the start of the recording.
4) If you have a false start, press STOP and then start the Recording again, delete any recordings
that you do not want.
